You need current disabling when a motor isn't moving...makes a *big*
difference.

see http://www.microstepping.com/sherline/2000cnc-2.stm


Then again, stepper motors are designed to get hot, so it's really nothing
to be worried about.
Except if you accidentally brush against one with your forearm when it's at
200 degrees.
